Perhaps you should try some spelling variations:
gain yang » dan yang, daun yang, tan yang
wang yang » wang yan, wang liang, wang yanling
kang hai » dang hai, kang han, shang hai
yang xi » yang di, yang yi, yang jui
xi kang » jin kang, xi zhang
yan n » yan _, jan n
yan 4 » yang 4, yan _, ban 4

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((yan n) OR (yan 4)) gain yang xi kang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ((yan n) OR (yan 4)) gain yang xi kang hai ;*.
